BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a manufacturing method of trademarklabel, and more particularly to a manufacturing method of a trademarklabel which can be produced by natural rubber and artificial leather forshoes, bag and clothes.

2. Discussion of the Related Art

Generally, trademark labels adhered on the shoes or bags are produced byusing TPR, one of the synthetic resin. However it produces noxiousmaterials such as dioxin during incineration, so its use reduces byreason of environmental pollution. And yet proper materials andmanufacturing methods that can be substituted are not developed.

Additional features and advantages of the invention will be set forth inthe description which follows, and in part will be apparent from thedescription, or may be learned by practice of the invention. Theobjectives and other advantages of the invention will be realized andattained by the structure particularly pointed out in the writtendescription and claims hereof as well as the appended drawings.

To achieve these and other advantages and in accordance with the purposeof the present invention, as embodied and broadly described, amanufacturing method of trademark label of the present inventioncomprises a process of making rubber sheet which is produced bycompounding the ingredients of natural rubber composite, a process ofcutting the rubber sheet according to the design of trademark label, aprocess of spreading primer on adhesion side of cut trademark label anddrying at normal temperature for about 5 minutes, a process of spreadingbinder on the primer-spread and dried part of trademark label, a processof inserting the glue-spread trademark label into the cavity of metallicmold and gluing (first gluing process) the trademark label on artificialleather, a process of removing unnecessary impurities of trademark labelattached to artificial leather (by first gluing process), a process ofinserting trademark label whose impurities are removed into the metallicmold and hot-pressing at the temperature of about 150° C., and a processof refrigerating the trademark label hot-pressed on artificial leatherto the temperature of about 5° C.

The natural rubber composite is composed of Natural Rubber about 6,000g, Styrene Butadiene Rubber 5,000 g, Nitrile Butadiene Rubber 4,000 g,Zinc Oxide 1,000 g, White Carbon 6,000 g, Isopropanolamine 480 g,Butyl-p-Cresol 100 g, Stearic acid 150 g, Resin guaiac 500 g, CaO 2,000g, Mercaptobenzothiazole 70 g, Dibenzothiazyl Disulphide 200 g,Tetramethylthiuram Monosulphide 10 g, process oil P-1 3,000 g, Sulphur300 g in the above weight ratio and is made by roll-mixing them in aroll mixer.

It is to be understood that both the foregoing general description andthe following detailed description are exemplary and explanatory and areintended to provide further explanation of the invention as claimed.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings, which are included to provide a furtherunderstanding of the invention and are incorporated in and constitute apart of this specification, illustrate embodiments of the invention andtogether with the description serve to explain the principles of theinvention. In the drawings:

FIG. 1 is a process chart showing manufacturing method of trademarklabel of the present invention;

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to the preferred embodiment of thepresent invention, which is illustrated in the accompanying drawings.

FIG. 1 is a process chart showing manufacturing method of trademarklabel of the present invention. As shown in the figure, a trademarklabel (1) is manufactured by using artificial leather (2) and rubbersheet made of natural rubber composite.

An aluminum metallic mold is produced according to the trademark label(1) designed with specific logograms and figures. And then raw materialsof a trademark label (1) whose chief ingredient is natural rubber arecompounded.

Namely, the ingredients of the rubber sheet made of natural rubbercomposite is;

-   Natural rubber about 6,000 g,-   Styrene Butadiene Rubber; SBR 5,000 g,-   Nitrile Butadiene Rubber; NBR 4,000 g,-   Zinc Oxide 1,000 g,-   White Carbon, the color strengthener of natural rubber 6,000 g,-   Isopropanolamine, the plasticizer 480 g,-   Butyl-p-Cresol (BHT), the age resister 100 g,-   Stearic acid, the stabilizer and plasticizer 150 g,-   Guaiac resin, the antioxidant 500 g,-   CaO 2,000 g,-   Mercaptobenzothiazole, vulcanization accelerator 70 g,-   Dibenzothiazyl Disulphide 200 g,-   Tetramethylthiuram Monosulphide (TS) 10 g,-   Paraffinic process oil P-1 for antipollution and color stability    3,000 g,-   Sulphur, vulcanizing agent 300 g.

After all these materials are roll-mixed at the above rate in a rollmixer and vulcanized, the rubber sheet is produced.

After pressing procedure on the said rubber sheet by air-press, etc.,trademark label is formed by cutting procedure according to the logodesign.

As a preceding treatment procedure for gluing the trademark label (1) tothe artificial leather, ‘No 503 Primer’ manufactured by ‘KeojinCommercial Company’ in Korea is spread on the back of the trademarklabel (1) and it is dried for 5 minutes at normal temperature. And thenCRF hardener is mixed in ‘DS 5109 Binder’ manufactured by ‘DongsungIndustrial Company’ in Korea in the weight ratio of 0.5 percent, and itis spread on the back of the trademark label (1). After that, thetrademark label (1) is inserted in the cavity of an aluminum metallicmold which is of the same size with the trademark label (1), and theadhesion side of the trademark label (1) is covered with the artificialleather (2), and they are glued firmly by closing the metallic mold.

After gluing procedure of rubber sheet (that is, a trademark label) madeof natural rubber composite and artificial leather (2), the metallicmold is opened to remove all impurities except the trademark label (1)and it is re-inserted into metallic mold to be hot-pressed at thetemperature of about 150° C. on both side alternately. And afterrefrigerating press procedure to the temperature of about 5° C., thecompleted trademark label (1) is took out from metallic mold.

The advantages of the present invention are as follows.

The trademark label (1) that is made of rubber sheet produced by naturalrubber composite is firmly attached on the surface of artificial leather(2) without separation and any transformation such as a twist of productdoesn't occur.

And the trademark label (1) with softness of artificial leather (2) andquality of natural rubber is visually luxurious and it provides greatdistinction when compared to the ordinary trademark label (1) made ofsynthetic rubber only.

And the natural rubber is attached on the artificial rubber (2), so itcan reduce the weight of the shoes when it is used on the outsole of theshoes. Therefore it can take effect of reducing record when it isapplied to the outsole of sports shoes such as marathon shoes.

And it can reduce environmental pollution because it doesn't producenoxious materials such as dioxin during incineration.

It will be apparent to those skilled in the art that variousmodifications and variations can be made in the fabrication andapplication of the present invention without departing from the spiritor scope of the invention. Thus, it is intended that the presentinvention cover the modifications and variations of this inventionprovided they come within the scope of the appended claims and theirequivalents.
